I was in the same predicament. In the end I booked the month all zones ticket, because for the sake of a few pounds you can go where you want when you want. I am like you I fly out to Rome in 4 weeks and I plan to spend 3 months travelling but I havn't a clue where I want to go. Does anyone have any itinerary suggestions?
Sorry I havent been checking up on this over last ferw days, I've got my final uni exams at the moment so my trip has had to take a back seat for a while.... Basically we are travelling for 24 days, our proposed itinery is as follows:
Krakow, Auschwitz, Zakopane 5 days
Prague 2 days
Bratislava/Slovakia 3 days
Budapest/HUngary 5 days
Zagreb 2 days
Dubrovnik 4 days
Split 2 days
Gelli your advice so far has been great, had no idea about buying tickets to the border then on from there etc etc any more advice would be greatly appreciated. We arrive in Krakow on May 21st and leave from Split on June 14th.
Thanks as well to everyone else, maybe Ill meet some of you on the trip.....
